[Asterisk-Users] Outbound dialing issue with FXO

[Mike Clark]

We are installing a number of systems with 2 TDM04B cards. Have done all 
the isolation to unique IRQs, etc. All inbound calls seem to work fine. 
However, outbound calls are hit or miss. Sometimes they work fine and 
other times we get a "you must first dial a 1 or 0" message back from 
telco when dialing out standard POTS lines.

We are running AAH 1.0 which is Asterisk 1.0.7. Six Polycom phones are 
on the system. Any ideas on this one?
